Letters Patent No. 113,400, dated April 4, 1871,

IMPROVEMENT IN WATER-WHEELS.

The Schedule referred to in' these Letters Patent and making pari: ofthe same.

To all whom it may conce/rn Be it known that I, GARDNER Cox, ofPier-pont, in the cennty of St. Lawrence and State of New York, haveinvented a new and improved W'ater-Vheel; and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill' enable those skilled in the art to make and use the same,reference being had to the accompanying drawing forming part of thisspecification.

rlhis invention relates to a new and .improved waterwheel ot' that classwhich is secured to a vertical shaft, and consequently rotates in ahorizontal plane.

The invention consists in a peculiar construction of the buckets, and anovel application of them to the wheels, whereby a large percentage ofthe power of the water is obtained.

In the accompanying drawing- A represents a suitable base or platform,in which the lower part of the wheel is fitted and works.

B is the shaft of the wheel, the lower end of which is stepped in thecross-bar- O, iitted and seeured`tothe base or platform in which thewheel is fittedand works. n

The wheel is composed of a hub or hody,1, having buckets, G, attached toits exterior. This hub or body has a concave periphery, as shown clearlyin fig. 1, so that the hub or body gradually decreases in diameter in aconcave form from its upper to about 'lhe buckets G are each composed oftwo parts, e and b, the upper and longer parts, 11, being inclined at auangle of from five to thirty degrees with a horizontal plane orthe planeof rotation of the wheel, the

longer or upper buckets?) bending or'eurving down at the lower ends atc, the lower parts of the buckets a bending or curving up at the upperends, forming a4 connection at c. Theicenter, at c, forms nearly a tlatcymct frectft, which is shown clearlyin tig. v1.

The lower portions of these buckets, whiehinclnde-I the parts a b, are.similar `to those now employed in the ordinary turbine waterwheels, theextension or prolongation of the upper parts l) and the gradual increaseof the buckets Ifrom their upper to their lower ends, caused by theconcave-exterior of the body F, constituting the main portion of myimprovement.

Byhavin g the buckets ci b constructed and applied to theeoncaveexterior of the hub or body F of the wheel, as shown and described, thefull benefit of the force o i' the impact of the water is obtained, andalso the force or power due to the gravity of the water in its dischargefrom the wheel, the gradual expansion ot the buckets admitting of thefree discharge ot' the water, so that the latter cannot serve as adrawback to the wheel.

I 'claim as new and desire to secure by Letters Patent- The buckets a b,united at c' to the external cylin-Y der, arranged as shown, 'when saidbuckets areattached to the concave periphery of thedownwardly-diminishing hub or body F of a wheel, as and for the purposeMARY E. WELCH, HERBERT I. BROWN.
